Description
A braking resistor is used to dissipate the excess DC link energy in generator operation. The
braking resistors can be connected to a Braking Module or directly to a 20 kW or 40 kW
Basic Line Module.
Resistors with and without a thermostatic switch are available with various rated powers. The
thermostatic switch monitors the braking resistors for overtemperature and issues a signal at
an isolated contact if the limit value is exceeded.
